[SergeShkurko]

Package name
network

Describe the solution you'd like
The ability to use decorators for example: @get('http://todo.api/todo/1') / @post('http://todo.api/todo')

Additional context
Proposal example:

class TodoApi {
  @get<JsonApiRequest, JsonApiResponse>('http://todo.api/todo')
  Future<Iterable<Todo>> getAll(JsonApiRequest request, JsonApiResponse response) async {
    return List.from(response.toMap).map((map) => Todo.fromMap(map));
  }

  @get<JsonApiRequest, JsonApiResponse>('http://todo.api/todo/${id}')
  Future<Todo> get(JsonApiRequest request, JsonApiResponse response) async {
    return Todo.fromMap(response.toMap);
  }

  @delete<JsonApiRequest, JsonApiResponse>('http://todo.api/todo/${id}')
  Future<Todo> delete(JsonApiRequest request, JsonApiResponse response) async {
    return response.toMap['success'] != null;
  }
}
